Hubble Finds Dark Matter

Astronomers say hefty gas giant is 100 times heavier than the sun

(NEWSER) - The most massive star yet discovered has been "weighed," astronomers say, and it tips the scales at a whopping 114 times the mass of the sun. The enormous star forms the bigger half of a rapidly orbiting binary system and it far outstrips both its companion star and the previous record holder—which weigh in at 84 and 83 solar masses, respectively.

(NEWSER) - A nearby solar system looks a lot like ours, complete with newly identified asteroid belts, gas giants, and a similarly sized sun, Space.com reports. The star at the center of the system is visible without magnification, and scientists say they can infer the presence of planets in a zone whose conditions would be hospitable to life. "This system probably looks a lot like ours did when life first took root on Earth," a researcher tells McClatchy. More»

15-mile-wide black hole is smallest ever found

(NEWSER) - Astronomers have spotted the smallest black hole ever discovered, Reuters reports. It is just 15 miles across—the size of a city—but still has a pull strong enough to "stretch your body into a strand of spaghetti," said a NASA researcher. The relative pipsqueak weighs about as much as four suns, while black holes often weigh billions of times more. More»

Unprecedented spacewalk will make for spiffier 'scope

(NEWSER) - Astronauts will save—and drastically upgrade—the Hubble Space Telescope in an unprecedented mission this year, NewScientist Space reports. The mission will make the Hubble 90 times more powerful than it originally was, but will require spacewalkers to complete a delicate electronics repair job in zero gravity while wearing bulky spacesuits. Without the tune-up, Hubble would go offline by 2011. More»

Images are twice as sharp as Hubble's

(NEWSER) - A ground-based optics system has been developed that can take pictures of space twice as sharp as those from the Hubble Telescope. The system uses advanced light detection chips and calculates when the atmosphere is least distorting, the BBC reports. The system gathers together the clear pictures and eliminates distortions to produce what researchers believe are some of the clearest images ever obtained. More»
